What are example of anime characters you hate but enjoy the performance? I am asked not dubbed or subbed but dubbed and subbed? That is, not either but both.

One for me is Shippuden's Tobi. When he's in he's serious true persona, I absolutely hate a character that is so manipulative and arrogant. However, I love Wataru Takagi's portrayal of Tobi as a comical coward. If you think about it, when it comes to Naruto getting to full power and facing Tobi without any interruption, Tobi should be acting like a coward.

Similarly, regardless of why he did it, Itachi ranks as one of my most hated anime/manga characters for murdering his family (even if this is a fictional character, slaughtering your entire entire family is morally detestable and just so wicked). However, his arrogant persona when he was battling Sasuke before he finally died was something I felt that Crispin Freeman nailed that part.
